Thanks to a great deal of planning and coordination, winter placement of a massive foundation mat for Columbia Center No. 2, a 14-story office building in Troy, Mich., went without a hitch. The 21,000-square-foot mat was placed in November, at a time of year when Michigan weather is always unpredictable. But weather wasn't the only worry. Because the building was part of an office complex and surrounded by existing high-rise structures, parking decks, and parking lots, the concrete placement had to take place on a Saturday, when office traffic is minimal. This gave concrete contractor Simone Contracting Corp. only 1 day to place the nearly 3,200 cubic yards of concrete required for the 4-foot, 2-inch-thick mat.
